First off, get rid of the parasol, please! It doesn't match at all. Perhaps if there was some pink on the rest of your outfit. Secondly, you may want to consider wearing a blouse; you're showing too much skin below your neck.

Edit: Oh, I just noticed; the shoes are a bit strange. They don't look as if they belong. I'm not sure if they contradict guidelines to a Lolita style, however.
